Case study:

The automobile manufacturer Mahindra & Mahindra came out with a new Sports Utility Vehicle (SUV) SCORPIO. This was at a time when the company was financially drained out and the market was saturated withSUMO SAFARI AND TOYOTA QUALIS. Due to these reasons the manufacturers were skeptical about investing in new production facilities, although the distributors urged the manufacturers to build more vehicles. The other reason was also the price of the vehicle when it first came out on the market which ranged from Rs. 6, 60,000 to Rs. 8,50,0000.

The bad years of Mahindra had taught the management to be more risk averse than risk prone. The manufacturers are performing well again and investing in new ventures.

Would the demand follow in the long term or would customers stop demanding Scorpio when the next fad comes along? The lack of diversification and the high cost base had affected the company adversely in the past. Thus the management was afraid that the decision to invest was too early. On the other hand, investing would help Mahindra & Mahindra to expand and become the market leader in this particular segment.

A study was conducted in 2 metros of the income group of the customers who bought SCORPIO which is as follows:

 METRO (CITIES) INCOME-GROUPS TOTAL RICH MIDDLE POOR DELHI 10 30 160 200 MUMBAI 40 120 140 300 TOTAL 50 150 300 500

a. Define the Management Decision Problem and the Researcher’s Problem Respectively.

Ans:

b. State the research question and formulate the associate hypothesis.

Ans:

c. What type of research has been conducted by the researcher by the management to come up with a decision? Justify your answer.

Ans:

d. Critically evaluate reasons for collecting the income of the customers and the type of sampling design used by Mahindra & Mahindra.
